Enrollment for Quantitative Fluorescence Microscopy 2022 at the MDI Biological Laboratory in Maine is now open. QFM is an intensive lab/lecture course, focusing on fluorescence microscopy in all its forms, including widefield, Confocal, Multiphoton, Decon, Super resolution TIRF, FRET, 2D and 3D image processing (including time-based analysis), etc., with an emphasis on live cell methods. We also encourage students to provide their own specimens such that the hands-on components of the course are as enriching as possible.
